I am creating a class that validates strings. There are many reasons why the string might not pass.
Would it make more sense to throw an exception, or return false/error code? Pros/cons?

validators should not throw exceptions, as failing a validator is not an “exceptional” event.
the rest of your code should throw exceptions if it gets bad data.
when you run a validator function you are clearly prepared to handle any problems detected with a simple test. wrapping everything in a try/catch block and stopping all execution only to try to recover is overkill. Just use and if statement, and be prepared to show the user some error messages.
